The Short Version
The claim significantly understates how many men can bench press 140 kg. Multiple sources estimate that roughly 1% of men can bench ~136 kg (300 lb), and scaling competition data against broader training populations suggests approximately 0.2–0.5% of all adult men can reach 140 kg — still rare, but meaningfully above the claimed 0.1% threshold. The 4 kg gap between 136 kg and 140 kg does not justify a tenfold drop in prevalence. The claim exaggerates the rarity by a factor of 2–5x.
